1. The Conjuring (2013)
This modern classic is based on the Perron family haunting in Rhode Island. Paranormal investigators Ed and Lorraine Warren, known for their involvement in the Amityville case, were brought in to investigate disturbing events: moving furniture, slamming doors, and ghostly apparitions. The Warrens documented their experiences extensively, giving the filmmakers a rich archive of terrifying real-life inspiration. According to Wikipedia, the Perrons believed their home was plagued by the spirit of a witch named Bathsheba Sherman.
2. The Exorcism of Emily Rose (2005)
This unsettling courtroom drama-horror hybrid tells the story of Anneliese Michel, a young German woman who underwent 67 Catholic exorcisms before dying from malnutrition. The film blends horror with philosophical and legal questions, forcing the audience to wonder: was it possession or mental illness? The real-life Michel’s case shocked Europe and remains one of the most documented exorcism cases in modern history.
3. The Amityville Horror (1979)
When George and Kathy Lutz moved into their new Long Island home, they believed they had found paradise. But after only 28 days, they fled, claiming demonic forces haunted them.

The Amityville Horror is one of the most well-known horror movies that is based on a true story, even if skeptics continue to question the authenticity of the Lutzes’ claims.
4. The Texas Chain Saw Massacre (1974)

Gein, a reclusive farmer in Wisconsin, exhumed corpses and used human remains to create furniture and clothing. While Leatherface and his family are fictional, the grotesque imagery and twisted psychology were drawn from Gein’s real-life atrocities.
5. Veronica (2017)
Set in Madrid, this Spanish-language film follows a teenager who uses a Ouija board during a solar eclipse. Afterward, she experiences terrifying visions and is believed to be possessed.

Her case remains unexplained, and Spanish police documented some of the supernatural claims in their official report.
6. The Haunting in Connecticut (2009)

The Warrens were once again involved in the investigation, claiming the house was infested with evil spirits from its days as a mortuary. Whether you believe it or not, the events were so dramatic they became the basis for this unforgettable film. The Wikipedia entry details many of the supernatural elements the film incorporated.
7. Deliver Us from Evil (2014)
This film follows NYPD officer Ralph Sarchie, who uncovers demonic activity in New York while investigating a series of connected crimes. Based on his real-life accounts detailed in his book “Beware the Night”, the film merges police thriller with demonic horror. It raises chilling questions: what if evil isn’t just psychological or criminal, but spiritual as well?
